Improvement in machines foh making metallic nuts

gauge, which, as before stated, is the end of the edge swage c, and lying on the anvil:

First, the edge swages which act opposite to each other, come into position to steady the rod.

Second, the moving jaw of the 'shears descends, and also the crown-swage, the former cutting on" the blank, and the latter giving it a slight shaping-blow.

Third, all the edge swages strike the nut a blow, and retreat.

Fourth, the crown-swage descends further, and retreats, shaping the top ofthe nut, while, at the same time, the punch descends, so as to prevent any part of the blank being forced into the hole in the crownswage, through which the punch works.

Fifth, all the edge swages strike again, and retreat.

Sixth, the punch descends, punches the hole, and retreats.

Seventh, the shear-jaw and crowning swage and punch retreat to their furthest position from the nut, and the edge swage b, acted upon by the highest projecting part of the cam e, acts as a transferrer, and shoves the nut off of the anvil and over the hole a?, through which it drops. This edge swage retreats as soon as it has shoved the nut over the hole, and all parts then assume the positions shown in the drawings, so that the rod may again be forced forward, preparatory to the formation of another nut.

I have already said that the parts active in forming or forging the nut may operate in any desired order, and I also wish it to he u'nderstood that the number of times of operation may be varied; for instance, the edge swage may strike one or more blows, and so may the crownswa; ze. And not only may the order, but the relative time of operation be changed; for instance, the nut may be hammered while held upon the punch, and may be hammered on all sides at once, or on only two sides at a time, as specially described; but in all cases the blank is to occupy the same locality from the time of shearing to the time of completion.

I claim as my ow'n invention- 1. The combination ofthe edge swages, crown-swage, punch, and shears, when so arranged, substantially as described, in relation to each other, as to act upon the blank lying in the same spot, while all the necessary operations upon it are performed.

2. In combination with edge 'swages, punch, crown swages, and shears, arranged as described, the aperture in the bed-plate or table, and the cam, to give additional motion to one of the edge swagesf so that it acts as a transferrer to discharge the nut.
